Game.Vehicles.Passenger

Assembly:
Assembly-CSharp (Unity game assembly)

Namespace:
Game.Vehicles

Type:
struct

Base:
Implements Unity.Entities.IBufferElementData, System.IEquatable, Colossal.Serialization.Entities.IEmptySerializable

Summary:
Represents a passenger entry stored in an ECS dynamic buffer for vehicles. The struct wraps a single Unity.Entities.Entity reference (the passenger entity) and provides equality and hashing implementations. The struct is annotated with [InternalBufferCapacity(0)], indicating no preallocated inline capacity for the buffer (purely dynamic).

---

Fields

• public Unity.Entities.Entity m_Passenger
  Holds the Entity reference that represents the passenger. This is the value stored for each buffer element.

• Attribute: [InternalBufferCapacity(0)]
  Specifies the internal buffer capacity for the dynamic buffer type. A value of 0 means the buffer has no small-object inline capacity and will allocate dynamically as needed.

Properties

• (none)
  This struct exposes its data via the public field m_Passenger; there are no C# properties defined.

Constructors

• public Passenger(Unity.Entities.Entity passenger)
  Initializes a new Passenger buffer element with the provided passenger entity.

Usage: Construct this when adding a passenger entry to a DynamicBuffer.

Methods

• public bool Equals(Passenger other)
  Implements IEquatable. Compares this instance to another Passenger by comparing their m_Passenger Entity values.

• public override int GetHashCode()
  Returns the hash code of the contained Entity (m_Passenger). Useful when Passenger instances are used in hashed collections or comparisons.

Remarks / Notes

• Implements IBufferElementData so instances are intended to be stored in Unity's DynamicBuffer attached to entities (for example, a vehicle entity's passenger list).
• Implements IEmptySerializable (from Colossal.Serialization.Entities) to participate correctly in the game's custom serialization system.
• Equality is based solely on the Entity field; two Passenger instances referencing the same Entity are considered equal.

Usage Example

using Unity.Entities;
using Game.Vehicles;

// Add a passenger entity to a vehicle's passenger buffer
public void AddPassengerToVehicle(EntityManager entityManager, Entity vehicleEntity, Entity passengerEntity)
{
    // Ensure the vehicle has the buffer (AddBuffer will create it if missing)
    var buffer = entityManager.GetBuffer<Passenger>(vehicleEntity);
    buffer.Add(new Passenger(passengerEntity));
}

// Check if a vehicle already has a given passenger
public bool VehicleHasPassenger(EntityManager entityManager, Entity vehicleEntity, Entity passengerEntity)
{
    if (!entityManager.HasComponent<Passenger>(vehicleEntity))
        return false;

    var buffer = entityManager.GetBuffer<Passenger>(vehicleEntity);
    foreach (var p in buffer)
    {
        if (p.Equals(new Passenger(passengerEntity)))
            return true;
    }
    return false;
}
